IMPROVEMENT IN REVERSlNG-LINKS FOR STEAM-ENGINES.

Specification forming part of Letters Patent No. 160,358, dated March 2, 1875; application filed June 20, 1874.

To all whom it may concern Be it known that I, J OHN SrMPsoN, of Meadville, Crawford county, Pennsylvania, have invented a new and Improved Reversing-Link for SteainEngines, of which thefollowing is a specification:

The invention relates generally to valve gearing, but particularly to that shown in the patent No. 125,769.

The invention will first be fully described, and then pointed out in the claim.

Figure 1 Ba sectional elevation of my improved reversing-link, taken on the line x 00, Fig. 2; and Fig. 2 is a sectional elevation, taken on the line 3 y, Fig. 1.

A represents the two slotted links, having a large circular recess at each end of the slot, and bolted to a block, B, and also together at each end, by a bolt, (3. E represents the notched pivots of the eccentric rods F, one of which is fitted in each end of the link, and G represents the collar in the middle of each pivot, fitted between the two plates to hold the pivots in p1ace, n1aking a simple and cheap contriva-nce, well adapted for durability. I is the wrist-pin of the valve-rod, which works in the notched pivots. One of the blocks B, to which the plates are fastened, composes the eye H, by which the link is suspended with a cord or chain, J, and one of the bolts constitutes a handle, K, for shifting the link by hand.

Havingthus described my invention, I claim as new and desire to secure by Letters Patcut- The combination links A, having slots, bolted to a block, 13, and made circular at each end, in combination with the eccentric rods F, having notched pivots E, and the collar G, as and for the purpose specified.

JOHN SIMPSON.
